Definitions

  • the invention relates to a hollow-chamber plate with cover surfaces arranged at a distance and parallel to one another and in each case arranged at the same distance parallel to one another and connecting webs connecting the cover surfaces to one another.
  • Hiebei can be single or multiple hollow chamber plates.
  • Such hollow chamber sheets made of thermoplastic material that can be produced in the economical extrusion process are widely known and have already been used, for. B. proven as a replacement for glass or as additional glazing.
  • the object of the present invention is now to create a hollow chamber plate of the type described at the outset which, with only a slight increase in weight, has substantially better strength values.
  • This is achieved according to the invention in that the inside of at least one cover surface has a curved course between the webs, a circle which can be written into the cross section of the connection region of the webs to this cover surface with tangential contact with both the outside and the inside of the cover surface having a radius , which corresponds to about 1 to 4 times the thickness of the web.
  • Such a hollow chamber plate surprisingly has an increased flexural strength, in particular in the direction transverse to the longitudinal direction of the web, wherein if only one curved inner side is used, this is always turned towards the outer side in use.
  • the arched course of at least one inside of the top surface creates, in particular, an increased resistance to buckling of the top surface regions lying between the webs.
  • the hollow chamber plate designed according to the invention has a stiffness in the transverse direction that is almost the same as the stiffness in the longitudinal direction of the web. Larger areas can advantageously be covered without supporting elements.
  • the radius corresponds approximately to the thickness of the web, the thickness of the middle area of the cover surface lying between two webs corresponding to at least 0.5 times the thickness of the web, preferably the thickness of the web.
  • curvature cross section is symmetrical with respect to a central plane running in the longitudinal direction of the web.
  • the arrangement can be such that - seen in cross-section - the curvature of the curved inside has a continuous course from the connection area of a web to the middle surface area between two webs. This enables a further increase in the rigidity or a design with less material expenditure with the same rigidity.
  • another embodiment of the invention is characterized in that the spacing of the webs from one another is approximately twice as large as the spacing of the two top surfaces from one another.
  • the hollow chamber plate 1 is formed from two cover surfaces 2, 3 arranged parallel to one another and from webs 4 which run perpendicular to it and are arranged parallel to one another. In the area of intersection of the webs 4 with the upper cover surface 2, the inside of which is curved.
  • This curvature can be seen in cross section, for. B. correspond to the course of an ellipse or a line course composed of at least two cross arches.
  • connection of the curvature to the vertical wall of the web is made with a curvature equal to zero.
  • a circle 6 can be written into the mass accumulation of the intersection area, which tangentially touches both the outer surface of the upper cover surface 2 and the curved inner surface.
  • a radius 7 of the circle 6 is one third larger than the thickness a of the web 4.
  • the upper cover surface 2 is used as the outside. If wind pressure, precipitation, in particular snow or the like cause forces in the direction of arrow 8 on the hollow chamber plate 1, then there is a bending stress which leads to a tensile load on the lower cover surface and a pressure load on the upper cover surface 3 or 2 .
  • This pressure load in the longitudinal direction of the webs 4 can be counteracted in a satisfactory manner by their high bending strength.
  • the situation is different in the transverse direction of the hollow chamber plate 1 extending in the longitudinal direction of the web.
